Joules Formula Physics ~ The english physicist james prescott discovered that the amount of heat per second that develops in a current carrying conductor is proportional to the electrical resistance of the wire and the square of the current. In science the joule is the unit of energy or work. 1 joule per millisecond 1000 watt 1 kw kilowatt 1 joule per microsecond 1000000 w 1 mw megawatt. Here the unit joule is equivalent to a unit amount of watt for a unit second. The formula for kinetic energy in joules is pretty straightforward. It is equal to the energy transferred to or work done on an object when a force of one newton acts on that object in the direction of the force s motion through a distance of one metre 1 newton metre or n m. 1 joule per second 1 watt. Joule s law is given by. The joule dʒ aʊ l dʒ uː l jowl jool. There are 4 19 joules in every calorie. Indeed lately has been sought by consumers around us, perhaps one of you. Individuals are now accustomed to using the internet in gadgets to view image and video data for inspiration, and according to the title of the article I will talk about about Joules Formula Physics. 1 joule per millisecond 1000 watt 1 kw kilowatt 1 joule per microsecond 1000000 w 1 mw megawatt. Joule s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy. Joule s law is given by. It is equal to the work done by a force of one newton acting through one metre. The formula for kinetic energy in joules is pretty straightforward. For example you could work out the mass of a bowling ball and then drop it off a building to work out what its velocity is. There are 4 19 joules in every calorie. Named in honour of the english physicist james prescott joule it equals 10 7 ergs or approximately 0 7377 foot pounds. Current location physics formulas electromagnetism joule s law.

The english physicist james prescott discovered that the amount of heat per second that develops in a current carrying conductor is proportional to the electrical resistance of the wire and the square of the current.
The english physicist james prescott joule discovered in 1840 that the amount of heat per second that develops in a wire carrying a current is proportional to the electrical resistance of the wire and the square of the current. Joules can also be converted from calories as calories are another unit of energy. It is also the energy dissipated as heat when an electric. 1 joule per second 1 watt.
